SV-91819r2_rule The SUSE operating system must prevent the use of dictionary words for passwords.

Vulnerability discussion

If the SUSE operating system allows the user to select passwords based on dictionary words, this increases the chances of password compromise by increasing the opportunity for successful guesses and brute-force attacks.

Check content

Verify the SUSE operating system prevents the use of dictionary words for passwords. Check that the SUSE operating system prevents the use of dictionary words for passwords with the following command: # grep pam_cracklib.so /etc/pam.d/common-password password requisite pam_cracklib.so If the command does not return anything, or the returned line is commented out, this is a finding.

Fix text

Configure the SUSE operating system to prevent the use of dictionary words for passwords. Edit "/etc/pam.d/common-password" and add the following line: password requisite pam_cracklib.so

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
